Abstract
The invention relates to copolymers based on N-substituted acrylamides, N-substituted methacrylamides and N,N-disubstituted acrylamides and to a method for their manufacturing, which copolymers are prepared under conditions when the phase separation takes place. The resulting copolymer contains reactive groups and serves as the intermediate for preparation of biologically active compounds (enzymes, hormones, drugs, etc.) bonded to the polymer. The procedure according to the invention enables to prepare porous polymers suitable as separation barriers (membranes) or column packings for gel or affinity chromatography, if the polymerization is carried out in the presence of a divinyl component.
